Unformatted text preview: The Physics of Light & Sound Introduction Speed, velocity, and acceleration are three important quantities when studying the motion of any object. The average speed of an object describes the distance traveled within a certain time but does not contain any information about any changes in direction. The velocity is a vector quantity that also contains directional information. Most objects do not travel with a constant velocity but rather have accelerated motion. The acceleration is deFned as the variation of the velocity in time. In this experiment, you will study the motion of an object with constant velocity and also motion with constant acceleration. One of the most effective ways to study motion is to produce plots of position vs. time, velocity vs. time and plots of acceleration vs. time. ¡rom such graphs it is possible to determine the direction an object is traveling, how far it has traveled, and whether or not it is speeding up or slowing down. In this experiment, you will use a motion detector coupled with a computer to plot in real time a graph...
